PAPER FOR USE IN TYPE-WRITTEN WORK TO OBTAIN MANIFOLD COP IES.

Patented Feb. 11, 1908.

Application filed May 4. 1904- Serial No. 2063301.

have invented a certain new and useful Improvement in Paper for Use inType-Writ ten Work to Obtain Manifold Copies; and declare the followingto be a full, clear, and exact description of the same, such as willenable others skilled in the art to which it pertains to make and usethe same, reference being had to the accompanying .drawings, which forma part of this specification.

My invention relates in general to writing paper and more particularlyto a sheet of patype-written matter.

It is customary when it is desired to produce duplicate copies oftypewritten matter to interpose a sheet of carbon paper between twosheets of blank paper, the three sheets being then inserted between theplaten and copying ribbon. The original copy is made on the outer sheetby the t e forcing the ribbon against the same, whi e the second copy ismade by the carbon paper upon the inner sheet owing to the impact of thetype transmitted through the outer sheet. This method is objectionableas it requires considerable time to arrange by hand the superposed blanksheets and interposed carbon paper and then insertin the series ofsheets in the type-writing mac ine. The handling of the carbon papersoils the hands of the operator and a so frequently soils the innersheet of blank paper when the series of sheets are placed around theplaten.

It has been proposed heretofore to obviate the use of carbon paper inmaking duplicate copies of type-written matter by surrounding the platenof the typewriter with a covering impregnated with coloring matter andproviding a roll of a continuous transparent sheet of paper which ismoved around the platen coincidently' with the movement of separatesheets of the usual ribbon an the continuous sheet of paper. Duplicatecopies of the matter written upon the successive separate sheets areimpressed upon the continuous sheet from the copying material around theplaten. This method is objectionable in that all transparent copies areon a continuous sheet wound around a roller thereby necessitating thecontinuous sheet being cut into pieces corresponding with the separatesheets on aper inserted between order that corrections may be made inthe duplicate copies and in order that such duplicate copies may befiled.

The primary object of my invention is to provide a sheet of paper uponwhich duplicate copies of typewritten matter may be made without the useof interposed carbon paper, the two copies being made on superposedportions of the sheet of paper such portions being detachably securedtogether, thereby permitting corrections to be readily made in bothcopies and facilitating the filing; of one copy owing to its being on apiece of paper of convenient size for handling.

A further object of my invention is to provide a sheet of writing paperupon which duplicate copies of typewritten matter may be made, whichwill be simple in construction, inexpensive in manufacture, andeflicient in use.

My invention generally described consists in a sheet of writing papercomprising two superposed portions detachably secured together, theunder portion being transparent so that characters impressed upon theback thereof may be read through the same. My invention will be morefully described hereinafter with reference to the accompanying drawingin which the same is illustrated as embodied in two convenient andpractical forms, and in which,--

' Figure 1 isa plan view of a sheet of paper embodying my inventionbefore being folded; Fig. 2 a perspective view of the sheet of paperwhen folded preparatory to inserting the same in a typewriter, and Fig.3 a plan view of a modification.

Similar reference characters are used to designate similar parts in theseveral figures of the drawing.

Referring more particularly to Figs. 1 and A 2, reference character Aindicates one portion of a sheet ofpaper which may be substantiallyopaque, translucent, or of any suitable character for receivingimpressions from the type of a machine of any usual or ordinaryconstruction. Detachably secured to the portion A is a transparentportion'B, the two portions together constituting a sheet of paperadapted to be inserted with the two portions super osed, in atypewriting machine around t e platen thereof.

The platen of the typewriter in which my invention is to be used must beprovided with a copying material, such for .instance as a ribbonimpregnated with pigment or other coloring matter secured around thesurface thereof. The sheet of paper is so inserted in the machine thatthe transparent portion B underlies the portion A and engages thecopying surface on the platen.

After the insertion of a sheet of paper embodying my invention thetypewriter is operated in the usual manner which results in simultaneousimpressions corresponding to the type being made upon both portions ofthe sheet, one on the portion A due to the type forcing the usual ribbonagainst the same, and the second copy being produced on the back of thetransparent portion B owing to the impact of the type being transmittedthrough the two portions of paper to the platen.

The two portions of the sheet are detachably secured together so thatafter the sheet of paper has been removed from the machine the twocopies may be separated, the original on the portion A of the sheet fortransmission and the duplicate copy on the transparent portion to befiled for record. The two portions of the sheet may be detachablysecured together in any suitable way, such for instance as by providinga line of perforations or indentations between the two portions asindicated in Figs. 1 and 2, or by merely securing the two portionstogether by an adhesive made and reference character B indicating thetransparent portion.

From the foregoing description it will be observed that I have inventedan improved sheet of writing paper bymeans of which duplicate copies oftypewritten matter may be produced without the use of carbon paper, bothcopies being made on pieces of paper of a size convenient for the makingof corrections and for filing.

Having now fully described my invention, what I claim as new, and desireto secure by Letters Patent is:

1. An integral sheetof paper consistingof a substantially opaque portionand a transparent portion, said sheet provided with a series ofperforations by which the transparent portion maybe readily separatedfrom the opaque portion, substantially as described.

2. A-doubled, integral sheet of paper, consistingo'f a substantiallyopaque portion, and a transparent portion, contacting with each otherwhen folded, said paper provided with a series of perforations along thefold whereby the transparent portion may'be readily separated from theopaque portion, substantially as described.

In testimony whereof, I sign this specification in the presence of twowitnesses ARTHUR J. FARMER. Witnesses: I
